2532 6103 d 18 h jermar /trunk/ VFS work.

The VFS_REGISTER is now fully implemented by both vfs and fat servers. Thanks to
the debugging dprintf()'s, I was able to fix little errors here and there to
make them actually work.

Modified vfs and fat service makefiles so that the two are not built as drivers
and can therefore print to standard output. Added many debugging dprintf()'s.

Change the amd64 boot configuration to load vfs and fat.		  
2531 6104 d 17 h jermar /trunk/uspace/ VFS work.
Implement VFS_REGISTER part of the protocol in the FAT file system.

IPC work.
Rename ipc_data_send_accept() to ipc_data_receive() and ipc_data_send_answer()
to ipc_data_deliver(). Introduce ipc_data_send().		  
2530 6105 d 8 h jermar /trunk/uspace/lib/libc/generic/ Pseudo thread -> fibril change in several comments.  
2529 6105 d 20 h jermar /trunk/uspace/ Turn the empty fs service into the beginning of FAT support.
Start implementing the VFS protocol for fat.c.		  
2528 6105 d 20 h jermar /trunk/uspace/lib/libc/ Modify parts of the build system and libc to support building applications on
paths with differing distances from lib/libc (e.g. uspace/srv/ns and
uspace/srv/fs/fat).		  
2527 6107 d 2 h jermar /trunk/ VFS work.

Added mandatory VFS_LOOKUP

Handling of VFS_REGISTER request should be now more or less complete.
Added code that inserts the new fs_info structure into the list of registered
filesystems and creates a callback connection to the client FS.		  
2526 6107 d 22 h jermar /trunk/uspace/ VFS work.
Delve deeper into VFS_REGISTER.		  
2525 6107 d 23 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalnum().  
2524 6108 d 0 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalpha().  
2523 6108 d 4 h jermar /trunk/ VFS work.

Now, each VFS connection fibril will accept requests in a loop. The idea is that
each connection will be potentially reused for multiple requests before it is
closed by the server.

More VFS_REGISTER bits. Make use of the IPC_M_DATA_SEND wrappers introduced in
the previous commit.

Add enum members for more VFS operations.		  
2522 6108 d 6 h jermar /trunk/uspace/lib/libc/ Add wrappers facilitating easy use of IPC_M_DATA_SEND calls and answers.  
2521 6109 d 17 h jermar /trunk/uspace/srv/vfs/ VFS work.
Start implementing the VFS_REGISTER request.		  
2520 6109 d 18 h jermar /trunk/uspace/ VFS work.
Turn the dummy skeleton into a dummy skeleton that can handle connections.
There are already traces of the VFS protocol.		  
2518 6110 d 17 h jermar /trunk/uspace/ One occurrence of the left-over term 'pseudo thread' replaced with 'fibril' in
the rd task.

Start the vfs task. Now it is dummy, but integrated into the sources.		  
2495 6172 d 21 h jermar /trunk/uspace/lib/libc/generic/io/ Formatting changes.  
2492 6178 d 20 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2491 6178 d 21 h jermar /trunk/uspace/ Fix two minor bugs in uspace's make clean.  
2490 6180 d 20 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2489 6180 d 23 h jermar /trunk/ Allow HelenOS to be built by a native gcc on Solaris.  
2488 6182 d 15 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2486 6182 d 19 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.		  
2485 6186 d 16 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6186 d 18 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6186 d 21 h jermar /trunk/uspace/lib/libc/ Remove fibril_join().
We cannot guarantee our assumptions that easily.
This broken feature is removed instead of fixing because there are now users of it.		  
2482 6187 d 12 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.		  
2481 6187 d 14 h jermar /trunk/uspace/lib/libc/ 1. Implement simple joining of pseudo threads. Only one pseudo thread is allowed to join another pseudo
thread. The restriction is that both pseudo threads must be from the same thread (this is to simplify
synchronization). The joiner doesn't free anything from the joinee. It only gets its return value. Not
tested thoroughly yet.

2. Cleanup of a dead pseudo thread is done by the next scheduled pseudo thread. Not tested thoroughly yet.		  
2480 6192 d 0 h jermar /trunk/uspace/ Remove dummy presenter.  
2479 6192 d 0 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2478 6193 d 20 h jermar /trunk/uspace/rd/ Add sanity checks for reads and writes that occur past the end of the
ramdisk image.		  
2476 6194 d 16 h jermar /trunk/ Cleanup.  
2475 6194 d 16 h jermar /trunk/uspace/rd/ Improve the rd task (not tested):
- allow more connections
- support write operation
- support concurrent requests
- sanity checks
- add comments

Please review.		  
2471 6197 d 18 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)		  
2470 6201 d 16 h jermar /trunk/ Fix a double-free recently introduced in revision r2436.
Add a comment clarifying the life-cycle of the kernel_uarg structure.

Comment out the freeing of userspace thread stack while still running on it.
This should be fixed by implementing userspace version of thread_join().		  
2469 6201 d 17 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.		  
2468 6201 d 19 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.		  
2465 6206 d 22 h jermar /trunk/ Merge arm32 into trunk.  
2449 6213 d 4 h decky /trunk/uspace/rd/ remove unnecessary includes  
2445 6213 d 23 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)		  
2443 6214 d 14 h jermar /trunk/ sscc -> suncc  
2442 6214 d 15 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
